They have verbally said that they can build us a turnkey house for £1600/m2, which suits our target budget, but I'm concerned that this will not be to the spec we want and by the time we add the extra insulation I know we will want and any individualisation it will be a lot more than we have budgeted for!
The alternative, to self manage with subbies, is difficult for me to cost as we would need to get to building warrant stage before we can get reasonably accurate quotes, by which time we will have passed the point of no return and I don't want to have to reduce the spec at that stage to hit our budget target!
A few years ago I'd have been more confident and handled a lot of the work myself but when you get into your 70s this becomes more of a challenge. We are lucky that we have access to some really high quality tradesmen who we have used in the past.
It's a small plot, only 21m 22m so we want a build with a relatively small footprint as we'll still have to meet requirements for two parking places and turning space etc.
